UNIVERSAL TAP wnENcH.

Application led May 9, 1924. Serial No. 712,119.

The present invention relates to a tap wrench and aims to provide a device of this nature having a shank of two sections flexibly connected together in order that the device may be utilized to advantage in assembling metal fixtures of all kinds. In this work there are holes that have to be tapped that cannot be donewith the ordinary wrench but because of the flexible connection between the two sections of the shank of the present wrench places which are ordinarily inaccessible are made accessible in order that holes may be tapped therein.

The invention also aims to provide a very simple and efficient device of this nature which may be easily and readily operated, one which is inexpensive to manufacture, durable, strong, and well adapted to the purpose for which it is designed.

Another important object of the invention is to provide means for holding the flexibly connected sections of the vshank of the wrench in alinement with each other when desired.

With the above and numerous other objects in View as will appear as the description progresses, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing, Figure 1 is an elevation of the tap wrench embodying my invention showing portions in section, and

Figure 2 is a transverse section therethrough taken on the line 2 2 of Figure 1 looking in the direction'of the arrow.

Referring to the drawing in detail it will be seen that the shank of this wrench. is formed in sections 1 and 2 which are prei'- erably of hollow construction and their adjacent ends are provided with bifurcations or ears 3 pivotally connected with a block 4 byl means of pins 5 thus forming a universal joint which I indicate generally by the lette-r B. A sleeve 6 is slidable over the sections of the shank and Amay be held entirely over section 1 so as to in no way interfere with the operation of the universal joint B. If the sleeve is placed as shown in Figure 1 that is over both sections l and 2 it holds these sections in alinement with each other so that the wrench may be used as any ordinary tap wrench. The free end of section l is provided with a flat head or disk 7 to aid in turning the shank. The lower end of the section 2 is provided with external threads for receiving a collar 9. A set screw 10 is adapted to pierce the collar 9, the end of 4section 2, and also a core 11 0f a bit 12. By'this means there may be provided several different sizes in the bit all having the same sized core to fit the wrench. These cores are provided with openings for receiving the set screw l0 as is clearly illustrated in Figure 1.

When the sleeve 6 is disengaged from th universal joint B and section 2 it will be seen that the wrench is capable of being used with the sections 1 and 2 angularly disposed in relation to each other in order that holes may be bored by the bit 12 in places which would be inaccessible with the ordinary wrench. It is evident that changes in the details of construction and in the cornbination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

A tool holder consisting of a pair of tubular members of equal diameter but unequal lengths and having proximal ends formed with projecting ears, the ears of one member projecting into the spaces between the ears of the other member, a block located between said ears, pivots passing through said earsl and engaging said block, a collar screwed on the end of the shorter member remote from the ears and projecting peripherally of said member, a head on the corres onding end of the other member, a tool old- `ing bushing in the collar provided end of the first member, a screw passing through the wall of the collar, the first member and sleeve and servinglto hold the sleeve from unscrewing from t e first member, the bushing in sald first member and engageable with the shank of a tool inserted in the sleeve, and a tube slidable on said members, said tube. being longer than the shorter member and shorter than the longer member, and resting normally on the projecting part of said collar.
